The more we know....

MIT researcher finds neuron growth in adult brain

First we thought you never got new brain cells as an adult - then in 1998 that was proven false, and now this.

As much as we think we know - the reality is that we don't know squat. But we're getting more knowledge all the time, so maybe someday it will all begin to fit together.

You've got to be kidding me...

Researchers investigate the case of the disappearing teaspoons

This has nothing to do with brain research - except that some people's brains were clearly bored and needed something to do.

Neuronal baby-steps

New neurons take baby steps in the adult brain

Dropping in Stem-cells or other new cells into an area and just letting them go to work doesn't....well...work. It isn't that easy, you have to know how to make them turn into the cells you want, then you have to convince them to act like the other cells, and interact with them.

All-in-all - a complicated and very unstable process. However, this is definitely good news.

Bigger is better...

Bigger brain size matters for intellectual ability

I seem to remember a number of studies where they concluded that brain size and intelligence didn't matter. This most recent study contradicts the older assumptions.

I'll be interested to see if this gets replicated by other studies in the near future.

Leap-Frog anyone?

Does baby 'get' tech?

The conclusion of current research? We don't know. There is no evidence that electronic media (games, videos, etc.) actually enhances, or even assists in baby brain development.

They stay that actual time with your baby without tech is still the best.

Those of us with kids roll our eyes and say "Duh!"

Alzheimer's is a new form of Diabetes?

Alzheimer's: A New Form of Diabetes?

Now, I'm no expert on Alzheimer's, but it seems to me that this could potentially be an incredible breakthrough. If it is indeed a form of diabetes that could provide some clues as to how it could be treated.

Let's stay hopeful that this is a positive development.

What to ignore

Discovery disproves simple concept of memory as 'storage space'

Apparently better memory may not be about storage volume, but more about being able to have the ability to filter out useless information and pick out only the things that are worth transferring to awareness.

In other words: smart people are better at ignoring things.

You see Tomato...I see....Tomato

Everyone’s eyes are wired differently

And yet, despite actual physical differences in how our eyes are wired, we perceive color pretty much the same. I posted about this previously, and this only enhances my prior questions - is our perception of color a neurological, physical, or cultural thing?

Nature, nurture...blah, blah, blah....

And this is your brain on Hypnosis....

» Watching the brain under hypnosis

Basically, the brain shows direct evidence of perception of things that are not there. Personally, I'd like to see this linked to false memories as well.

So, now we have images of our brains under stress, and under hypnosis. We also have fMRIs of brains under the influence of various drugs and alcohol including addicted brains. We have images of brains under various types of psychological disorders (depression, schizophrenia, autism, etc.).

So, what's left?

Maybe a brain image of somone in love, under the influence of metaphysical effects...the list is probably pretty endless, and there are likely images of stuff I don't know about.

Ain't medical technology fun?

This is your brain on Stress...

UPHS News: Penn Research Permits First-Ever Visualization of Psychological Stress in the Human Brain

We have lots of studies on the effects of stress on cognitive performance (e.g.: Yerks-Dotson) - but actually getting an IRB passed through that allows us to put a subject under psychological stress and then look at their brains through an fMRI is definitely a good thing.

I wonder what that proposal looked like:

Q: What are the potential harmful effects to the participants?
A: Um...well...stress, for one....

Gaming the future

Researchers use brain scans to predict behavior

The upshot of the article is that fMRI scans seem to show when a brain is planning ahead and anticipating moves in a game.

So, we have identified a future perspective cognitive process in the brain as it relates to a specific type of game.

The Zen of Brain development

Meditation associated with structural changes in brain

Studies have shown that mediation can produce alterations in brain activity, and meditation practitioners have described changes in mental function that last long after actual meditation ceases, implying long-term effects. However, those studies usually examined Buddhist monks who practiced mediation as a central focus of their lives.

Studies also found that, in an area associated with the integration of emotional and cognitive processes, differences in cortical thickness were more pronounced in older participants, suggesting that meditation could reduce the thinning of the cortex that typically occurs with aging.

Gaming education

Games turn geography into child’s play

This is a personal project of mine, and one that I think has a LOT of room for growth. Games are not incorporated into education nearly enough.

And don't even get me started on using gaming technology.

Young or old - we can all be distracted

Changes in brain, not age, determine one's ability to focus on task

"We found that both performance and brain-activation differences of older good performers and the older poor performers are predicted by changes in brain structure, specifically by the volume of white matter connecting the right and left hemispheres of the frontal lobes,"

So - regardless of age, focus is a matter of how your brain is built.

Atlas of brain unfolds

New online atlas provides collective maps of human brain folds

While obviously not a "map" as such, seeing as each individual brain's folds are akin to fingerprints in thier uniqueness, but still, a pretty cool. The "map" images are based on averages so there is still a significant amount of data that could be derived from the images.

Blue...no, Yellow!

Color perception is not in the eye of the beholder: It's in the brain

"Researchers at the University of Rochester have found that the number of color-sensitive cones in the human retina differs dramatically among people--by up to 40 times--yet people appear to perceive colors the same way"

This is pretty cool. It brings to mind a study I read and can't find currently of a particular tribe of South American natives that only had language for 2 or 3 colors - green, not green and red. They couldn't really understand other colors like orange or variations of shades of green.

Perhaps the colors we percieve and how we percieve them are related to nurture rather than nature - to find that out would prove to be very interesting indeed.

Sticks and stones....

But apparently the words you use CAN hurt you - at least that's the gist of this study on how labels shape our attitudes toward violence.

Politicians have known this for ages. How you name something, or how you frame it affects the perception of the idea. Think of (for a controversial example) the abortion debate. You aren't pro or anti-abortion you are "pro-life" or "pro-choice" - the words describing the two positions don't refer in any way to the actual concept they are defining.

But, it turns out that it's even deeper than that - the nouns and adjectives we use can be powerful cues to how we make sense of people's behavior.

Emotions rule....everything

Humans are governed by emotions—literally

This actually comes as a surprise to nobody. I can't think of any decisions by any government, ever, that weren't driven primarily by emotional reaction.

Seems like we're coming to a much more complete realization that emotions play a much larger role in our everyday actions than what anyone would have supposed.

Smoking makes you stupid

Well, according to this University of Michigan study: Does smoking cloud the brain? The answer seems to be, yes.

It's long term and it seems that the toxins enter the brain and hasten cognitive decline. So, if you smoke - prepare to get less intelligent more quickly as you grow older.

Of course, putting a known toxic and carcinogenic substance like tobacco smoke into your system willingly argues for a certain lack of intelligence to begin with - but that's just my opinion.

I'd be interested to see this

Maths and science education gets animated and collaborative online

It's about freaking time. I look out on the web-based learning landscape and I see very little that is truly new and innovative. The main idea seems to be stuck in the mode of online Skinner Boxes.

I'm not sure what the solution should be - but the environment described in the article is pretty cool.

Because the fulcrum isn't aligned with the axis.....

Okay - sorry for the exceptionally obscure quote. I'm not even sure where it's from myself, but I remember it from my childhood in Saudi Arabia. It was a BBC made cartoon for kids, something about a kid with a ball or some such child-oriented basis. The episode revolved around a bully of some sort that was demanding that someone build a box that was actually an optical illusion, the young boy with the ball patiently explained to the ogre that the build was impossible because "the fulcrum doesn't align with the axis" - a statement that he then wen ton to explain to the clueless ogre.

All that is simply the long way of leading into this article: New book explains age-old mystery of geometrical illusions

A finding I think is pretty cool. Check out this marvelous last quote:

The problem for colleagues in physiology and anatomy is that our theory runs counter to what they've been doing for the last fifty years," said Purves. "And their response has understandably been 'Well, OK, that's interesting. But how do you relate this concept of vision to physiology and this anatomy?' It's perfectly valid to say, 'You've got a nice idea and it does explain the phenomenology of what we see, but how does that relate to the neurons that we know and love?'

"The answer is, we don't know," said Purves. "That's going to be the next many years of vision research. It will mean constructing a framework that explains how neurons and the connections among them operate in service of this complex, evolved statistical process called vision.

"Some bright people will certainly do this in the next ten, twenty or thirty years," said Purves. "I don't expect to be around to see it, but inevitably that will happen. But it's going to take people who deeply understand statistics and computer models of neural systems to develop a working theory of how the properties of neurons and anatomical connections are related to the end product of vision.

My brain made me do it.

Yea...that's the ticket!

Indeed.

Evidence of a 'memory code'?

UCI neurobiologists uncover evidence of a 'memory code'

Looking at the text of the article you find that their findings are a bit on the macro level to really be calling their findings a "memory code" - but their findings may hint at such a thing. I mean, equating the "importance" of a tone with the amount of auditory cortex devoted to processing that tone hardly seems to point at a "memory code" in my opinion. But hey, baby steps....

Scientific Savvy In U.S.

Well, this clearly isn't good news.

For an amusing and disturbing look at this same phenomenon, check out this link.

Have you ever watched the Jay Leno bit where he walks up to people on the street and asks them very simple questions about subjects that I consider common knowledge (basic questions of U.S. history or questions about current affairs or about the city they live in), and the people he shows on TV are so clueless it's downright painful to watch.

It's amusing, and I like to think that these people are the exception and not the rule - but it looks like the percentages of clueless people is much higher than I'd like to admit.

Women are more complex than men

Well, in their voices anyway: ScienceDirect - NeuroImage : Male and female voices activate distinct regions in the male brain

Key quote:

The female voice is actually more complex than the male voice, due to differences in the size and shape of the vocal cords and larynx between women and men, and also due to women having greater natural ‘melody’ in their voices. This causes a more complex range of sound frequencies than in a male voice.

When a man hears a female voice the auditory section of his brain is activated, which analyses the different sounds in order to ‘read’ the voice and determine the auditory face.

When men hear a male voice the part of the brain that processes the information is towards the back of the brain and is colloquially known as the ‘mind’s eye’. This is the part of the brain where people compare their experiences to themselves, so the man is comparing his own voice to the new voice to determine gender.


Pretty cool.

Ignore everything on this site....

Well, maybe not everthing, but then there is this: Most published research findings may be false

Not terribly surprising when you think about it. Most publishing is really just hypothesis gathering - and much of what I report here is really on the fringe of science as far as emerging discoveries. The article probably applies even more in psychological or neurological settings as our level of understanding of basic concepts like "consciousness" or "creativity" is still vague at best.

This phenomenon is also extremely valuable to consider when looking at scientific findings or topics that are highly politically, socially or culturally charged.

Let us all marvel....

...at the collosal stupidity of this British researcher's report

Now, I'll be the first to look very curiously evidence of gender difference - but using IQ measurements? Is he being serious?

Let's look at what he says:

Dr Irwing, a senior lecturer in organisational psychology at Manchester University, said he was uncomfortable with the findings. However, he said, the evidence was clear, despite the insistence of many academics that there were no meaningful gender differences in levels of intelligence.

"For personal reasons I would like to believe men and women are equal, and broadly that's true," he said. "But over a period of time the evidence in favour of biological factors has become stronger and stronger.

"I have been dragged in a direction that I don't particularly like, but it would be sensible if the debate was based on what we pretty much know to be the case."


Again, I'm all for challenging accepted wisdom if you have credible evidence on your side. But using IQ scores is NOT a credible way of providing evidence in this case. All he has shown is the females score lower on IQ tests on average. So, isn't it just a little possible that the instrument you're using might just be flawed at being able to measure "intelligence" levels between men and women? Isn't it possible that IQ tests show very little regarding an individual's intelligence outside of their ability to successfully complete an IQ test? Is that the only measure of "intelligence" that you used?

Here's for all you MENSA folks out there - and IQ test shows nothing more than your ability to take an IQ test. That's all. Certainly a form of "intelligence" but not the only or even best indicator.

I will be a very happy man if the perception of IQ tests could ever be turned on its head.

Neural Communication - do we really understand it?

This article (free registration required) indicates that neural cell communication occurs in other places besides the synaptic endings.

The scientists at the Salk Institute for Biological Sciences at UC San Diego found that nerve cells release neurotransmitters outside of synapse, a process they call "ectopic neurotransmission" (which is just fun to say - especially if you're Bill Murray).

A few years ago it was discovered that glial cells played a stronger role in communication than was previously thought, and now this - we're going to have to re-write a few textbooks once we figure out what all of it means.

I know what you're thinking - but just read the article. It basically is saying that certain types of erotic (or even "exotic") images grab your attention more aggressively and hold it, basically creating a temporary bottleneck of sensory perception. The effect also seems to be greater for some individuals and lesser for others. Thrill seekers (extreme sports enthusiasts) for example don't seem to be affected as much.

Being able to generating that type of bottleneck for less erotic subject matter (read: public education curriculum) would seem to be a fantastic way to generate long-term learning.
